Well, I've got a couple of my HQ units customized. Here, have a Master of the Forge on a bike, with a conversion beamer!

Theoretically there's supposed to be a bunch of old fashioned "chocolate chip" desert camo on there, but since this is a new camera and I have no idea how to use it, it looks more like a pile of stupid. I'll post more pics of that and my captain once I figure out how to not wash out all the colors, and maybe how to get it in focus.

I look forward to you giving some Tau a taste of their own medicine with that. I'm not up to scratch with the current version of 40k so you'll have to tell me exactly how killy it is. I'm going to go with "really, really" until then. Is the beamer itself a conversion, or have they released a model for it?

No official model for it atm. It's made from a variety of different IG sentinel parts, the ends of a couple necron guns, a devastator squad lascannon, and a lego lightsaber blade. But yes, very killy, sometimes! Str 6 no AP up to 18", Str 8 AP 4 up to 42", and Str 10 AP 1 up to 72", and it's a blast weapon.

The captain is on a trike for no real good reason, and his command squad all have choppers! I'm forcing myself to put off any more HQ units after that until a make about a billion regular bikes. I am taking brief break from bikes at the moment though, to turn one of the AoBR dreadnoughts into an Ironclad.
